One of the main reasons i would like to have a tank spec for shamans is because theyre a hybrid class. It could be easy to make a Warrior healer using shouts and morale boosts, or Mage tanks with magical barriers and other magics. But you dont pick a warrior if you want to heal, or a mage if yoy wanted to tank. But as a Shaman, i like to do it all. And all of the tools are already there. Just a few tweeks and Shamans have plenty of spells, armor, and thematic reasons to be tanks
And because most tanks feel like they have a niche, Shamans could be about weapon buffs. Just a thought
I could see switching weapon enhancements on your shield and 1hander to determine what you need at the moment. And depending of the combination between the two, effects what spells excel at the moment.
For sake of bloat, only two elements per weapon/shield.
Weapon: Fire-Passive aoe damage. Better resource generation
Weapon: Water-Healing Spells enhanced. Auto attacks passively heal
Shield: Earth-Damage Mitigation. No spell interruption
Shield: Air-Lightning/chain lightning do more damage. Earthquake causes static electricty to do more damage/threat
Also, depending on the combination of enhancements, you could gain access to, or enhance, one of your current spells. Having Water Main hand and Air Shield could cause your healing rain to turn into healing storm, AoE that heals allies and damages enemies.
To be able to switch between your enhancements, it only needs 1 button per slot. Switch your main hand to other enhancement. And switch you off hand to the other enhancement.
I think Shaman tanks could be really awesome. Any thoughts on this please share them. Even if you dont like it, that can spark insight as to how it could be great or improved.
